Most of the artificially made luminous balls are made of fluorescent powder (commonly known as glow powder), which is divided into two categories: photoglow storage powder and luminous powder with radioactivity. Photoglow storage luminous powder is phosphor in the environment after natural light, daylight, ultraviolet light, etc., the light energy stored, after the cessation of light irradiation, in the slow release of fluorescence, so at night or in the dark, can still see the luminous, the duration of a few hours to a dozen hours.

There are mainly 3 categories of phosphors for lamps. The first category is used for ordinary fluorescent lamps and low-pressure mercury lamps, the second category is used for high-pressure mercury lamps and self-ballasted fluorescent lamps, and the third category is used for ultraviolet light sources, etc. There are many types of phosphors, and the price is different, phosphors have good thermal stability, safety and environmental protection, for a variety of white light, can be adjusted to different red, blue, yellow and so on the color.
